Speedmaster heads for SBM

Everything is relative.
A head guy I know has a 1.94 intake valve 10 to 1 Nova at 3200-3300 pounds running 9.80’s wheels up with the factory iron heads on it in S/S.
He swears on small hole, torque and velocity in everything he does.
And to say he is well respected is an understatement.





He’s running SUPER STOCK. He doesn’t get the option of a bigger valve or port.

Aint no way on Gods green earth he’d be running that valve and port size if the rules didn’t mandate it.
